Title: Improvements in high pressure apparatus
IPC: B01J3/06
Filed: 1962-12-19
Abstract: 1,022,973. Very high pressure apparatus. ALLMANNA SVENSKA ELEKTRISKA A.B. Dec. 19, 1962 [Dec. 27, 1961], No. 47872/62. Heading B1X. A very high pressure apparatus comprises an annular pressure chamber defined by two end surfaces, side surfaces and a body centrally located along the axis of the chamber; said side surfaces being formed by the inner faces of inwardly movable pressure transmitting blocks and said end surfaces being formed by the faces of pressure resisting means which are sealed to said blocks and do not move along the axis in relation to said chamber when said blocks move inwardly. An embodiment illustrated in Fig. 6 (not shown) has an inner body of small compressibility in the form of a cylinder, centrally placed in the annular pressure chamber. In Fig. 1 (and Fig. 2, not shown), the pressure chamber comprises five sector-shaped blocks 100 having hardened sections 101, of conical outside section having gaps 102 between them, said blocks surrounding the material (graphite or molybdenum disulphide) to be compressed. The material is enclosed by annular layers 124 and 126 of talcum or pyrophyllite. The central body comprises a tapered peg 121 attached to hydraulic piston 108 which slides upwardly to force five annular, internally conical sections 123 outwardly whereby the material may be precompressed. The ring 156 contacts faces 157 of the blocks 100 causing them to be forced upwards. They are constrained inwardly as a result of wedge action with a corresponding shaped casing 111 and thus compress material 125. The interface 149 may be lubricated with graphite, molybdenum disulphide or oil. An opposing member 107 sliding within retaining ring 112 and having disposed between it and an end stop 115, a fluid medium such as oil or water admitted through valve 117, serves to control and contain the pressure around material 125. The pressure chamber may be cooled by a cooling medium passing through tube 133-136. Sealing means 142, Fig. 6 (not shown), serve to contain the material charge within the pressure chamber. The material 125 may be heated by passing a current therethrough when conductive, or by tubes, discs, threads, spirals or other bodies of electric resistance material embedded in the reaction mixture, current being supplied via conduit 145 to the piston 108 and led away via the piston 107 and a cable 146.

Traction and hoisting apparatus has a pair of cable clamping units 8, 9 whose jaw control members 16, 17 are pivotably connected at 24, 25 to a floating lever 22 in turn connected by a pin and slot to a reverse motion control lever 30. This arrangement prevents the floating pivot 28 of the lever 22 moving so as to simultaneously release both clamping units. In alternative embodiments the control lever is connected to the lever 22 by a universal joint, a lever and link, a parallel linkage, and a parallelogrammed-shaped plate. The floating pivot 28 can be connected by linkage to a pivot actuated by a detachable key or permanent handle to simultaneously release both clamping units. In the former case the keyhole is covered by a movable plate while the cable is in the apparatus or the apparatus is under tension, while in the latter case an abutment is provided to prevent rotation of the pivot under similar conditions by engagement with a boss on the pivot in order to prevent accidental release of both clamping units.

Title: Doffing device

Abstract: 965,166. Doffing apparatus. WILLCOX & GIBBS SEWING MACHINE CO. Dec. 28, 1962 [Feb. 23, 1962 ], No. 48764/62. Heading D1D. A device for doffing bobbins from a row of spindles comprises doffing means mounted to travel along the row and having an ejector adapted to be held below the bobbin to be doffed against the action of means urging it upwardly, and means controlled by the spindle to be doffed for releasing the holding means for the ejector to move rapidly upward and shift the bobbin off the spindle. As described, the doffing means comprises an ejector unit having three ejectors 39, Fig. 3 spaced apart at 120 degrees and each consisting of a forked member. Each ejector is carried by a slide 36 running in guides 37 bolted to a sleeve 32 rotatably mounted on a shaft 33. Each slide 36 is urged upwardly by a spring 40 fixed at its upper end to the sleeve and has a follower 47 running in a track 46 on the shaft 33. As the unit moves along the row, a star wheel 55 fixed to the sleeve is rotated by engaging the spindle to be doffed and the followers are forced down the cam-track tensioning the springs 40 until the lowermost one corresponding to the ejector 39 which now embraces the spindle slips over the bottom edge of the track and frees the ejector to be pulled upward by the spring. To adjust the point at which the ejectors are released, the effective height of the shaft 33 is adjustable relatively to the sleeve by rotating a plate 34 on a threaded end of the shaft, the plate being secured to a fixed part by bolts 34a in arcuate slots in the plate. To prevent counter-rotation of the sleeve by the pressure of the follower 47 against the cam surface of the shaft 33 under the influence of the springs 40, the sleeve is connected to the shaft through a clutch which allows the sleeve to be rotated one way comprising a spring 51 mapped around a collar 52 fastened to the shaft and a collar 53 rotatable on the shaft and fastened to the sleeve. Resilient stops 45 cushion the upward travel of the ejector-slides. Two ejector units are provided to operate on alternate spindles to reduce wear on the parts, the star wheels having twice as many notches as there are ejectors associated with it the ejector units are mounted on a carriage running on rails on the spinning- frame which has driving means and a guide and a shoot associated with each unit to conduct doffed bobbins to a receptacle in the carriage. To move each unit between operative and retracted positions, it is carried by a part 27 movable in fixed guides by rack-and-pinion mechanism operated hydraulically under the control of cams on the spinning-frame rails.
